3 Claims.

My invention relates to hand trucks and particularly to hand trucks ofthe horizontal multiple shelf type each adapted for supporting andtransporting a plurality of tray or rack units in relatively lixedrelation to each other, and to the truck, in a, manner permittingindependent removal of any one of the trays from the truck withoutdisturbing trays above, below, or at either side thereof.

Some of the objects of the invention are, to provide a truck of thistype which is simple in construction, rugged, and particularly adaptedto save time and facilitate the transportation and handling of yarnpackages and racks therefory in connection with the operation ofbraiding machinery.

With these and other objects in view, which will become apparent fromthe following detailed description of an illustrative embodiment of my20 invention shown in the accompanying drawings, the invention residesin a truck having therein the novel elements, features of constructionand arrangement of parts in cooperative relationship as moreparticularly pointed out in the claims.

In the accompanying drawings:

Fig. 1 is a side elevation of the truck;

Fig. 2 is an enlarged sectional plan view taken on the line 2-2, Fig. 1;

Fig. 3 is a transverse section taken on the line 3-3, Fig. l; and

Fig. 4 is a perspective view of a detail of the invention.

The truck, as illustrated in the drawings, is particularly adaptable forcarrying yarn package, bobbin or spool racks or trays of the typedisclosed in the applicants United States Letters Patent No. 1,966,247granted July 10, 1934, which comprises a substantially fiat rectangularskeleton frame I, provided with a plurality of rows of laterally spacedposts 2 adapted to enter center openings in yarn packages 3 forrespectively supporting the yarn packages, spools, or bobbins 3, invertical positions on the trays I.

The truck comprises, in the present instance, a substantiallyrectangular horizontal base I0 in the form of an open frameworkincluding longitudinal side beams II, II and transverse end beams I2,I2, preferably constructed of wood, which are secured together at thecorners of the 50 base lo.

Extending vertically from the four corners of the rectangular base IUare upright shelf-supporting posts I3, I3 and I4, I4 respectively, ofrelatively heavy wood; and extending vertically from each of the sidebeams II, II, intermediate the rear uprights I3 and the front uprightsI4, are relatively thin metallic uprights I5 which are provided withfooting elements I6 resting on .and secured to the side .beams II, I!respectively.

Secured to the inner transversely extending faces of each of thecorresponding pairs of end uprights I3 and I4, and to the oppositelydisposed transversely extending faces of the pair of intermediateuprights I5, is a series of transversely extending vertically spacedbars Il, Il, the vertical spacings of which are similar in eachinstance, and thereby positioning the bars I1 in horizontally alignedseries, respectively disposed in vertically spaced horizontal planes.

Secured to each bar of each of the horizontally aligned series oftransversely extending bars I'l, Il, at each side of the truck, is alongitudinally extending bar I8, in the present instance in the form ofan inverted channel bar having its weo I9 secured to the under sides ofthe bars Il and its flanges 2D, 20 projecting downwardly therefrom.

Secured to the longitudinal bars I8, I8, and extending transversely ofthe truck between the end and intermediate uprights I3, I5, I4, aretransverse bars 2I, 2|, which, together with the bars I'I, Il and I8, I8constitute a plurality of vertically spaced horizontal shelves 22, 22each adapted to support a plurality of trays I, I.

The transverse bars I 1 and 2| provide tracks or rails for supportingthe trays I, I, the bars I'I each having a single horizontal flange ortraysupporting rail I'Ia. The intermediate bars 2I are each providedwith a pair of horizontal traysupporting flanges or rails 2Ia, 2 Ia.

Extending vertically from the tray-supporting rails I'Ia of the bars I1,and from, and between the oppositely disposed tray-supporting rails 2Ia., 2Ia of each of the intermediate bars 2l, are guide rails Ilb and2I'b respectively, which guide the trays into and out of the truck,transversely thereof, and which separate and hold the trays againstrelative movement with respect to each other and with respect to thetruck longitudinally of the truck.

At the opposite ends of each of the cooperating tray-supporting rails I1a, I'Ib and 2Ia, 2IlJ` of the bars I1 and 2 I, respectively, are stopflanges or bumpers I'Ic and 2I'c, respectively, which ex.- tendtransversely of the bars and prevent longitudinal movement of the traysI laterally of the truck.

As shown in Figs. 1 and 4, the guide rails I'Ib and 2 Ib project abovethe top edges of the stops Ilc and 2 Ic for guiding the tray into thepockets transverse axle 3I carried by bearings or brack' ets 32 securedto the side beams II, II. Y The truck is provided, at the front end,with a pair of wheels 35, 35, mounted in castor frames" 35, 3S, whichare swiveled in bearings 31, 31 secured to the base I 0 in the anglesbetween the side beams II, II and end beams I2, I2 thereof,

respectively.

The front end of the truck, in the present instance, is provided with atransversely extending handle bar 4U carried at its opposite ends inbearings 4I, 4I secured to the uprights I4, I4 respectively.

Of course, the truck specifically shown and described can be changed andmodied in various ways without departing from the invention hereindisclosed and hereinafter claimed.

I claim:

1. In a rack adapted to support bobbin spindle trays of the type havinga base providing with its end members, handle means within the confinesof each of said trays at each end thereof, the combination of a seriesof shelves, four uprights mounted for mobility within which said shelvesare built, said shelves comprising a plurality of longitudinallyextending vertically spaced horizontal bars, a series of transverselyextending horizontal cross bars mounted on said longitudinal extendingbars, said last named bars together providing pockets for the receptionof bobbin trays, and undercut means at each end of the transverselyextending bars facilitating initial guiding of bobbin trays to thepockets, said transversely extending bars providing means shelves, ofmobile mounting means therefor,

means for initially and finally guiding and forming ypockets for saidbobbin spindle trays comprising cross bars adapted to be mounted inspaced relation on said longitudinally extending bars and provided withsupporting means and guiding means positioned vertically with respect tosaid supporting means, end members located vat each end of said bars andhaving a height less than the height of said guiding means thusproviding an additional initial guiding means for receiving said bobbinspindle trays.

3. In a rack adapted to support bobbin spindle trays and the like of thetype having a base provided with openings adjacent its end members whichfacilitates grasping of the end members as handles, the combination of aseries of shelves comprising a plurality of horizontally arrangedinverted channel bars extending longitudinally of the rack, a pluralityof uprights for supporting said shelves, a plurality of cross barsmounted 0n said longitudinally extending bars in such relation thattheir ends overhang at least some of the outermost longitudinallyextending bars, thereby providing open spaces between said cross bars tofacilitate grasping of the handles provided by the end members of thebobbin spindle trays, said cross bars also being provided with guiderails and end stops for said trays at both end of said rails of a heightless than said guide rails, for effecting initial guid ing of the traysupon insertion thereof to the pockets formed by said cross bars.
